Grade 7Science

Focus: In this unit, students investigate the phenomenon of digestion and other functions of the body and the causes of the sense of both health and sickness. The subtitle of this unit is How do things inside our bodies work to make us feel the way we do? Our sense of how our bodies feel throughout the day phenomena that students experience when they wake up, walk, run, feel hungry, and eat the wrong foods and the right foods. What is causes these bodily feelings to happen? How do we digest the food we eat? What is food, chemically? What happens to those chemicals in the body? This unit allows students to observe this phenomenon in detail and then start asking questions, formulating explanations, setting up and conducting activities and research, and working with classmates to analyze the shared experience and formulate new questions and developing new strategies for answering them. Students explore concepts that include the following:

  • What is going on inside our bodies to make us feel the way we do?
  • Why do molecules in the small intestine seem like they are disappearing?
  • What happens to the different molecules in food as it travels through the body?
  • Can problems in one body system cause problems in other systems?
  • Do all animals have chemical reactions to get energy from food like humans?

These include factual articles, history of the sciences, art and literature, spotting bad science in media and advertisements, graphics comprehension, research-type articles, reliability of sources, and other areas of science literacy.
